Prime Minister Shinzo Abe has been in office for five months and reporters who follow him every day still have one question: why hasn't he moved into the Prime Minister's Official Residence?

Despite his extremely tight schedule, a security detail-escorted limousine takes Abe to the prime minister's office every morning, a 15-minute ride from his private home in Shibuya Ward's Tomigaya district.

The question drew fresh public attention Friday after the Cabinet responded to a written query by Ken Kagaya of the main opposition Democratic Party of Japan, who asked if Abe's reluctance to move into the official residence had anything to do with rumors that it is haunted by ghosts.
